All day yesterday I could not download the newest ITunes version 9.0.2.25. This afternoon I disconnected all periperals to my PC and tried again. It worked!
Now, if I can just get the NVIDIA graphics driver to work....but NVIDIA does not have their drivers updated for WIN7.
It appears that most all other programs will work, except Adobe Flash.....with using Adobe Flash while in the 64-bit IE you get an error message....and have to open a 32-bit IE window to have Flash work.
